Answer: B. 1.33 minutes
Step-by-step explanation:
We have the following equation that models the motion of the pelican:
(1)
Where is the height of the bird and is the time in minutes.
Now, if we want to know he time the pelican will land on the ground, we have to solve the equation when :
(2)
At this point we have a quadratic equation of the form , and we have to use the quadratic formula if we want to find :
Where , ,
Substituting the known values:
Finally:
This is the time when the pelican will land on the ground
